Answer: For the capacity of your boat:
If the boat does not have a capacity plate, the following formula would be used:
Boat length multiplied by boat width divided by 15
(L x W/15)=
Number of people that can be safely carried in calm waters.
A suitable motor for the size of the boat:
15 - 20 hp (80-120 lbs)
Powerful workhorses that are still considered a part of the small outboard hp class. Outboard engines in this hp range are available primarily in 4-stroke configurations but may limited availability in 2-stroke configurations. Due to 2006 EPA regulations, outboard manufacturers are now required to build cleaner more efficient engines that meet strict emission standards. This hp range is quite popular for use with inflatable boats 10-14ft, aluminum fishing boats 12-16ft, jon boats 12-16ft in length, fiberglass boats 12-16ft in length. These hulls typically require a 15” short shaft length but may require a 20” shaft length as you approach 16ft in length. These hulls typically range in weight from 125-575+ lbs.
